Electronic Maximum Demand Indicator

The eMDI is a new approach and significantly enhances transformer monitoring. It is a fully electronic low power maximum demand indicator that records highest quarter hour values of transformer phase currents, together with transformer case and local ambient temperatures. Designed to meet the requirements of modern utilities’ networks, it couples data processing with proven wireless technologies to provide remote access of transformer load profiles.

The retrieved data provides intelligence in determining load trends, phase-load imbalances, comparative analysis for weather events and seasonal periods; enabling more efficiencies in capital budgeting, resource planning and management and hence future proofing against capacity constraints.
